A numerical mathematical model of the acceleration of the flow of gas - the carrier of discrete particles in the Laval nozzle to the required velocities in the ANSYS numerical simulation system and the main parameters of the gas and particle flow by the methods of computational hydrodynamics are developed. The result of this work is the preparation of a large mathematical model for accelerating the flow of gas - the carrier of discrete particles in the Laval nozzle to the required velocities, the profile of the Laval nozzle is calculated, the distributions of the main parameters of the gas flow and solid particles (pressure, temperature, velocity, etc.) and in the case of a collision with the sample surface. A numerical mathematical model is developed that is the main tool for determining the rational parameters of the process of gas and particle motion under various conditions, under which the required coating quality is provided.
